Re: Grounded Experimental Delta Printer
I couldn't contain myself. Here is a snapshot of the 3rd redesign of Simpson. He is looking pretty good. I need to add in some string, springs, magnets, hall effect sensors, spacers, bolts, and nuts....

Couldn't all the cons of a bowden be solved by a small light incremental encoder at the hotend? So many joints, I think the number of tolerances will add up, and I'm worried you will have a tough time...

I think I may have come up with a way to get rid of the spring. It means adding another piece to the arm. I'm not convinced this is a good idea. My test showed it performing well on the lift, but...

Re: Grounded Experimental Delta Printer
I came up with an improvement that can get rid of the the big spring. I was thinking about the arrangement above with strings in tension along a and b. Ideally a+b would be a constant but that only...

Rostock is now doing the right things, thanks to all the help from this forum. Now trying to calibrate the geared extruder by measuring the filament. Using 'Triffid Hunter's Calibration guide - After...

What speed are you trying to extrude at? Try something like 5mm/s to make sure you are not loosing steps.

I just realized that if I go with the quad-link arm above that Simpson will look like Bart Simpson. I am ordering yellow filament. Update: I have ordered all the non-printed parts. The printing is...

Bob, Not tried to extrude at any speed yet as the extruder isnt calibrated. When I try to extrude 100mm, only 16mm is extruded; wanted to get somewhere close to correct before trying to lay down plastic.

Re: Grounded Experimental Delta Printer
First, I have ditched the quadlink idea and have gone back to the simple two link arms. I just couldn't get my head around a simple design that didn't send my vitamin count through the roof. Not a...

OK. see your point. As pronterface uses mm/min, I estimate 5mm/s equals 300mm/min. I was already set at 400mm/min, but with the rate set at 300mm/min (5mm/s) as you suggest, the extruder still only...

Seemed to have sorted this by trial and error. Tried to calibrate extruder by sending different values using M92 Ennn. to firmware from pronterface. Eventually settled on M92 E635 which gives 101mm...

I keep hearing good things about QU-BD. After my first printer, I want to build a Delta. I will probably look into a QU-BD extruder kit.
